Application filed April 25,A 1910. Serial No. 557,330.

To all whom t may concern.'

Be it known that I, VILLIAM J. NnIDrG, a. citizen of the United States,residing at Madison, in the county of Dane and State of IVisconsin, haveinvented certain new andV useful Improvements in Type--Vriting Machines,of which the following is a specification. p

I Certain principles and features of my invention as described hereinare included within the generic vinvention which is described andclaimed in my co-pending application filed April 20, 1908, Serial No.428,212.

The objects of the invention as the same is more specificallyillustrated in the accompanying drawings are, first, to indicate to theoperator the distance to the bottom edge of his sheet from the currentprinting position, and this line by line and automatically, irrespectiveof the lengt-h of the sheet, and beginning a considerable distance fromthe end of the sheet; second, to give the operator a visual signal uponhis nearing the end of the sheet, and this automatically; third, 'tosupply him with a signal, preferably an audible signal, automatically,upon his bringing a Vpredetermined point upon the sheet into theprinting position; fourth, to render the machine inoperative upon thecompletion of his predetermined last line, also automatically; fifth, torelease the machine for further printing upon running out the completedsheet, automatically; sixth, to enable the operator to release theinoperative machine for further printing upon the sheet being printed,at will; seventh, to supply certain means adapted to make the inventionmore effective in its application and use, as hereinafter described; andeighth, to supply certain means adapted to be applied to othersheet-n1ovement-indieating uses of the same general character.

There is to-day no device upon the market to tell the operator how nearhe is to the bottom edge of his sheet until the edge itself comes intosight. I supply him with a practicable system of signalsl to prevent hisover-running his page upon his desired bottom margin, In addition Iindicate for him the extent of the unused space left upon the papersheet, beginning long before the time to remove it, and continuing tothe very end, so that he can look ahead and tell whether he has room onhis sheet for a group of matter like a footnote, or a table, or achapter heading, or the complementary close and signature. of a letter,that cannot well be divided, and thus can stop his page in advance ofthe predetermined `pagelength if need be, and this without preliminarycare on his part. This function has never before been performed, but isnovel to my invention.

I attain my several objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is an end view of oneembodiment of my invention; Fig. 2 is a detail view of certain parts;Fig. 3 is a top or plan View of certain portions of Fig. 1, with partsbroken away to show the mechanism for frictionally connecting my indiceswith the platen; Fig. 1 is a view similar to Figi 8. but shows amodification having the frictional connecting mechanism transformed intoa lateral clutch mechanism by the locking action of the adjunct latch115; Fig/5 is a front view of a portion ofFig. 1, in vertical section onthe line B B; the bell signal being omitted.

The embodiments of my invention which are shown and described hereincomprise a series of operative indices adapted to indicate progressivelywithinftheir range the extent of the remaining unused paperand Vhaving aconnection with the platen thatnormally causes them to move with theplaten but permits them to be detained or stopped independently of theplaten, a detaining means to stop them in a suitable initial or startingposit-ion, and a releasing means to release them at aA constant point inthe progress of the bottom edge of the sheet so that they'may resumetheir movevment with the platen. Added to these in- 80.

dices are' various signaling and locking means, together with otheraccessories intended to make the invention more useful, or more readilyapplicable to different ma-' chines under varying conditions ofoperation; v-

rl`he embodiment of my invention shown 1n Figs. 1 to 11 is described asfollows: The

lcarriage frame 12,'carried in the usual man ner upon the main frame llof the typewriting machine, has journaled in its ends disk 11b,attaching it fixedly to the platen by means of screws 103 (Fig. 6).Against this part 11b is placed the friction washer 11, made preferablyof a material like leather, and against the washer is placed anotherfriction-disk 11, shown separately inFig. 7, supplied upon the outerface thereof with the annular interdental depressions 51. I next mountupon the arbor 13 a composite part consisting of the bushing 42 and thedrum 6, the drum being fixedly attached upon the bushing and forming ineffect a single piece with it. The drum bears in a peripheral trough theannular band (Sab, which preferably is made of a material having smallinertia, like paper or thin celluloid. vThis band can be adjustablymoved upon the drum,having a frictional connection therewith; and itbears upon its surface indices and certain other markings, asy

will be hereafter explained. The adjustment provision is intended to addto the use-` fulness of the invention, but it is not an essential partthereof. f

With the drum I combine the following features: The bracket 100, locatedwithin the inclosure of the drum and attached to the outward shell-wallthereof by rivetsr 102,

has fastened upon it the radially-disposed shouldered pin 53 by means ofthe nut 53". .,''ournaled upon this pin is the hub 88, from the lowerportion of which radiate in differ- 6, adapted to engage with theinterdental depressions 51 in the disk 11, and thetaillever 54, Fig. 3,engaged by the spring' 7, which is more clearly shown in Fig. 11.

los

, ent directions the lever-tooth 52, Figs. 3 and This spring is attachedby one end to the t wall of the drum by means of the screw 9 and theadjusting nut 9, Figs. 3 and 11, and it acts through the engagement ofthe other end with the tail-lever 54 to press or actuate the disk 11upon washer 11a and upon disk 11b, the said parts engaging throughfriction surfaces thereon so as to give a frictional connection betweenthe .drum and the platen. A bend in the intermediate portion of thespring .7 makes contact with the outer wall of the drum, the said wallserv ing as an abutment from which the spring reacts. By turning the nut9 the tension of l the spring may be changed. Other forms of spriiiginaybe used in securing a frictional connection between my indices and theplaten, as for instance any one of the i springs shown iii Figs. 18, 31,34, 35, and

38, or a spring may be dispensed with and the fr'ctionfbe securedwithout it, as shown in 25,`32,.33, 38 and 37. lido not limit myselfwith respect to the form of the` spring, or With'reference to the othermeans of adjusting the friction to increase or` decrease it, and maydispense therewith. The

. friction may be other than a lateral friction, as shown in Figs. 25,31, 32, 36, 37 and V38.

y end 14. In order to return thislevervS l `into -itsopera'tiveposition, Il provide the contracting spiral' spring98 having one endthereof 'engaged'w'ith the said leverand the other end attachedto one ofthe walls of the drum, and thelever isr formed with the slot..

97 to work over the vstop-pin 93 on the lever 92, the said springop'eratingtohold one end of said slot against the said stop-pin with anydesired firmness. An opening 7 6 in the inner Wall of the drum permitsthe play of the projecting parts 52' and 14, while the opening 75 in theouter Wall of the drum permits the play of the frictionfshoe 96 and theparts bearing it. To cooperate With'the friction-Shoe 96a in a detainingaction described later, l place upon the carriage frame 12 the extension99, bearing the fric tion-surface 99a. The Washer 1 73, Fig. 6, on thearbor 13 holdsl the drum in an operative position laterally. j j

I attach to the carriage frame 12 by means of the screws 6l the frameextension 22,

' Figs. 1 and 10, bearing the inwardly projecting axle 20 (see Fig.10).' Upon this axle is lournaled the hub or sleeve 21j, bear ing thelixedly attached lever 7 4, the i'iredly attached piece 59 with itsprojecting stop` pin G2, the fixedly attached collar 105, and

the fix'edly attached lug-piece 17. Jouriialed upon the hub or sleeve.so as to turn freely thereon is also the stop or lever 15 with its lug63, the said lug bearing up- `ivardlv against the before-mentioned stopedly thereon is to permit of a backing-up movement of the projection 14when the platen is turned backwardly, as in backingup the sheet," thestop 15 lifting idly upward out of the way iny such a movement, landthen returning into position through the force of gravity. I do notlimit myself lo this particular means of providing for such a'backing-upmovement of the proj ect-ion 1l past the stop-lever 15. The stop-lever1:5

adapted toiact as a stop upon the projection 14, and it has a distinctlever function as Well.' Through it the projection 14 controls theposition 'of other parts, and is not merely fr controlled by them.plained, the' normal yposition of this lever or stop 15 `is in the pathof the projection 14, and it is supplied with means returning it intosuch` position. I do not however confine myself in all casesto the-useof a stop having any 'particular special chai-acteris'tics.

The part-s upon the `sleeve or hlt-1b 21 are returned into-operativeposition bythe' acf tion chiefly of thenspring 111, Figs. 1 and 10,which is attached at one end to thefranie v12; by the pin 112 and at theother end engaged with the lever 74, the said'lever being normally heldagainst the stop-pin 113- on i the frame extension, 22 `by the pullingaction of the spring, and kthis-more or less firmly according'as theleverage is increased or diminished by engaging the spring with thelever 74 farther from or nearerto the hub j" 21. The Weight 66 alsoassists infthis returning function. A. second function of the spring isto pull baclrivardly againstthe aotion of the projection'll- 'upon thestop 15, j

so as to subtract from the pressure upon the sheet. The Weight 66 alsoserves this func'- tion. The action of the parts thus far described iscontrolled by the sheet, through the `following `structurer- At the endof the sleeve l ent the paper-freeler cannotiooniplete its` movement butis stopped by the sheet. but when the sheet passes on the paper-feeleris left free to complete its'movement into a slot el, Fig. 1G.`in eithera papeutablo or a piece applied thereto: The preferable form of thispaper-feeler is that shown in Fig. l, in which the part 28. journaled onthe axis 20 and bearing the pin 23 and the stop-pin 2l, has journaledupon' the said pin23 the /papei-eiigaging portion y2S, the'l'ugl'thereon engaging vagainst the stoppin 24's() as 'to form alone-nayflexion means, or 'knee'joint The purpose of this joint 'is to providevfor a backing-np movement ofthe shoetibut it is to benotcd that thejoint mayl'icriunittcd, as'A ing the operativeness of the invention.rIhe eccentric weight G6 is connected with the paper-feeler in order toreturn the latter into the most convenient operative position, out ofthe way of the entering sheet, as shown in Fig, 1. The paper-feeler isoperatively ccnnected with the stop cr lever 15 through the stoppin 3G,Fig. 10, on the said weight, and the lug 17 cn the hub 21. The essentialfeatures of this portion of the mechanism are the paper-feeler, itsaxis, and the lever or stop 15. It is possible to omit the intermediatestop-lever 15 and the separate axis 20, by placing the paper-feeler uponthe same axis with the platen and giv-y ing it a path intersecting thepath of the paper vsheet direct, as shown in Fig. 31. I do not regard myinvention as limited to any particular form or forms of paperfeeler, norto any particular position therefor, nor to any particular manner ofconnecting the paper-feeler to act controllingly upon the indicatingmeans employed.

In order that the paper-feeler may move in a path intersecting the pathtaken by the sheet in cases in which the invention is applied tomachines in'which the paper-table S is unprovided with the slot 4 shownin Fig. 10, I attach upon the paper-table 8 the piece S', Figs. 1, 8 and9, containing the slot 4. This piece is shaped to hook around the rearedge of the paper-table, and its slotted portion lies upon thepaper-table as indicated in Fig. 1. The piece 8 is secured in place uponthe papentable by means of the set-screw 80. Other forms of slottedplates or auxiliary paper-backing that may be used with suitable formsof paper-feelers in such cases are illustrated at 82, Figs. 26, 28, 29,and at 8g, Fig. 80, described later.' I do not limit myself to anyparticular manner of providing for the action of the paperfeeler intothe paper-path. The paper-feeler I can be made to operate fromunderneath the sheet just as well, as illustrated in some of my gures.

Afirst it rotates step by step also.

The mechanism described automatically brings the paper-feeler into anoperative position permitting the introduction of the sheet, withoutinterference, a function that I believe no signaling mechanism employinga paper-feeler in connection with typewrit ing operations has beforeperformed, but that is novel to my invention. My backingup provision isnovel also.

The action of the structure thus far described is as follows: The sheetof paper 45 is entered into the machine in the usual Way down thepapentable 8, advanced in usual manner into printing position, andprinted line by" line as usual, the platen carrying forward the sheet inthe usual and well-known Way. As the drum G is connected fricticnallywith the laten, at Jventually however the projection 14 meets the lever15 in its path. At rst it pushes this lever idly ahead of it, impartinga turning movement to the hub or sleeve 21 and moving the paper-feeler28 in the arc 101, Fig. 1. It will be seen that if the paper sheet werenot present, the end of the paper-feeler would continue on into slot 4until the projection 14 cleared the lever 15, and the drum 6 wouldcontinue its movement with the platen. But during the presence of thepaper sheet over slot 4 the paper-feeler cannot thus enter the slot, butis stopped by the sheet. The lever 15 thereupon becomes a detaining stopin the path of the projection 14. By this time the friction-shoe 96a hasbeen carried fo-rward opposite the part 99 on the carriage frame. Afurther movement forward of the frictionally con nected drum 6mustresult in a turning of the lever 95 upon the pin 94, thus drivingout the shoe 96a against the friction-surface 99a. The resultantfriction will at once act detainingly upon the drum, so that thereafterless force than before Will be required to stop the drum against theforces tending to rotate it. The stop 15 will also act detainingly uponthe drum. But meanwhile another action is taking place, the pressure.

of the shoe 96a against the part 99 under the leverage of projection y14resulting in an inward pressure upon the end of lever 92, therebyopening up creasing the friction between the the acticn'of spring 7 Thatis to say, the friction between drum 6 and the platen is regulated underthe control of the sheet, varying accordingly as pressure is exertedupon projection 14 by stop 15, such pressure being increased to acontrolling extent during the cont-rol by the sheet of paper-feeler 28.These agencies acting together are calculated to detain the drum withthe miniagainst stop 15 and conthe sheet, and that is my purpose inusing all of them. And as the spring 111 acting upon the lever 74 addsstill another means of subtracting from the pressure of the paper-feeleragainst the mum of pressure sequently against vsheet,.I have a mechanismadjustable with the greatest delicacy and snreness to any conditions ofservice that may arise. My drum is now detained or stopped, and it willalways be stopped, necessarily, with the same point on its peripheryopposite the pointer 34. This point may be indicated by the small circleor index 89. In this position it remains during the presence of thesheet. Eventually, however', the sheet is advanced until the bottom edgethereof passes the paper-feeler 28. Instantly the paper-feeler entersslot 4, stop 15 ceases to act detainingly upon projection- 14, shoe 96a-is withdrawn by spring 98 from contact 'with the controlling partv 99,and the 'drum and the platen againstfriction between the platen and drum6, spring-actuated by spring 7, and no longer controlled or regulated bythe sheet, becomes of its original force, insuring the simultaneousrotation of the drum with the platen. It is clear that as the sheet isfurther advanced, drum G will be advanced cordinately therewith, andthat symbol S9 will be advanced away from pointer or index 3st andanother peripheral point be broughtl opposite it. This point can bemarked to indicate the distance remaining from the printing point to theend of the sheet, or to a point a xed distance therefrom. That is tosay, if the end of the sheet seventeen line-spaces distant from theprinting point at this moment, I can niark in v periphery 1T to indicatethis distance, and after another advance I can'mark the new `point onthe periphery 16 to indicate thelnew position of the sheet-end relativeto i the printing point, if the distance ,be sixteen line-spaces, and soon during the remaining progress of the sheet. I prefer to use indicesinvolving no mental calculation nor memorizing on the part of theoperator, suoli as the series of descending numerals shown. and I preferto use the line-space as a unit of measurement, but my invention is notdependent upon the use of any particular kind. or number o-r order ofindices.

lt is to beiioted that the mechanism described can be backed-up from anyposition of the sheet and to any required extent; the knuckle-jointconstruction of the paperfeelerv and the one-way stop provision in'connection with stop-lever permitting free backing-up of both sheet anddrum.

ilfljimcs. The mechanism described can be used upon the mostl delicatetissue fabrics without danger of injury. A mechaiiisinof suclrdelicacyof adjustment will ,not always lie needed, and indeed upon cerl tainclasses of work could not he used to the ,best advantage. For thepurpose of siiup.i fying the action of the mechanism I desire to showmeans whereby certain of the elev inentsshown as cooperating may ineffect be eliminated, and the mechanism used with- To this end I outthem, and this at will. place upon the outside wall of the drum e thelock-piece 16, Fig. 3, shown by dotted lines, in Fig 1, "pivoting thesaine stiliiy upon thepin 18 in such wise that it will retain anyposition given it. This piece when moved toward the periphery of. thedrum lies. away .from the lever-end 14', -but when shifted toiivard thearbor of the drinn it lies against thesaid lever and locks it, thusprevent'ing the action of the leverswit-hin the drum, "Whenr thus lockedthe projecting lever-endif acts as 'a fixed projection carriedbyhthedrum, and the connect-ion between the drum and the platen isasimple sirable.

frictional connection. The action is the same, essentially, thedifference being that there is no easing'of the friction between theplatenand the drum, and no cooperation of the part 99 in detaining thedrum, the entire work of detaining the .drum falling upon the lever 15.I show modifi-catioiisof this simpler combination of elements iiicertain of my figures. I also wish to provide means whereby the operatormay at will secure a more positive connection with the platen, as forinstance when tliesignaling oi' locking mechanism requires greater powerto operate than is afforded by the frictional connection, or when forother reasons a more positive connection with the platen is de- To thatend I supply the periphery of the disk 11 with one or more pivotedlatches 115, t-he same being pivoted at one end upon the pin 116, and atthe other end having a projection adapted to fit into the depressions117 in the periphery of the disk 11b. These latches are made preferablyof a resilient material, and are shaped conveniently for manipulation.Their purpose is to furnish a means of locking the disks 11 and 11btogether so that they will turn as a unit. W'hen this is done, as shownin Fig-4, the frictional connection between the platen and the drum G isin efiect'eliminated. As the tooth 52 is able to lift entirely freeofthe interdental spaces 51, and under the pressure of the. lever 95upon the lever 92 will always so lift free when the. said disks arelocked together andthe leverend 14 is pressed against by the obstructingstop 15, I have instead of an easable frictional connection a releasablelateral tooth/ed clutch connection between the drum and the platen. Thelock-piece 16 in this use must of course be shifted aside so 'as not tointerfere with the action of the le\ c1295.

Other 'indicating nimmt-In connection with in v indicesI employ certainsignaling and locking devices to notify the operator of the approach ofthe bottom edge of the eral sections in such a manner as to forni astriking contrast one with th other, the one preferably being coloredwhite with black indices thereon, and the other, 6, preferably beingcolored a solid black. By attaching the combined shield and pointer 34as shown, I conceal .thev section bearing the indices 6 from the eye ofthe operator during its period of rest, and then brin it into sight,along with the indices. This furnishes me with a very perfect signalingmeans, the

Ilsupply' 'it 'the eo tract-able stop 96c the lever 952L having the stop96e, and instead of bringing my levers into action primarily through thecoperation of the lever 15 with the projecting lever-end 14a, theprimary action is the action of the stop 99c upon the stop-lever 95d.l96e. This action pushes the projecting leverend 14a against the'lever 15until the paperfeeler 2S is vstopped by the sheet; after which thedetaining and opening action of the modification is likethat of Figs. 12and 13.

Fig. 15 is a view showing how the lever 95, together with the detainingpart thereon and the cooperating part 99 on the frame, may be omitted,the lever 92b itself being shaped to form the projection 141. In this.modification the lever 15 acts more directly upon the projectinglever-end 14b to open the friction between the disks 11 and 11b and todetain the drum 6.

F ig. 16 is like Fig; 15 in structure, except` modification thecope'rating part 99 on the frame is retained, but changed slightly inform. The spring for the friction is changed also in form. Part of thestructure involved is shown in cross-section in Fig. 18. The armeddished spring 7 holds the drum frictionally against the friction-disk11b through the agency of the sleeve-washer 106, upon which the drum isjournaled to'turn freely. The pressure of such a spring can be adjustedif desired by means of the washer 107: a simple" substitution of athicker or thinner washer will accomplish this adjustment. The leve-r95c is attached to the drum by means of the axis pin 94 in a mannersimilar to thatl already described. This lever terminates in africtionshoe 96, adapted to cooperate with the friction-surface 99d onthe part 99. The action is as follows: The projecting lever-end 14S.pressed upon in effect by the lever 15, operates the lever 95 so thatthe part 96d pushes inwardly upon the outer surface 99l of the part 99,which action has both la detaining effect upon the drum and also anopening effect upon its frictional connection with the platen, the drumbein lpulled outwardly away from the frictionisk 11"` by the leverageexerted upon thel pin 94.' In other respects the-action of thismodification is the same as has been described. j Y

Fig. 18 is like Fig. 17 in every respect, exfcept that all the leverswithin the drum are face'SO. The action of these beveled faces tends topush the drum outwardly from the friction-disk 11b, thus 4opening thefriction, and at the same time a. detaining action upon the drum isexerted. In this respect the modified mechanism is the equivalent ofportions of the mechanism. already described. It is possible to omit thebeveled faces from this modification, in which case the co-action wouldvbe merely a stopping action, like that of Fig. 1 when the projection 14islocked bythe latch 16, with no easing of the friction, the omitted#elements in thisv case corresponding to the eliminated elements in that.

In Figs.. 19 and 20 the arrangementy of parts is like that shown in Fig.1, except in the sheet-controlled elements, some of which,v

shown in Fig. 1 are here omitted, and lthe rej' mainder of whicharestationed under the platen instead of lover the papertable., The

frame extension 22a bears the inwardly project-ing axle 20E1 with itshub 21a. kUpon the hub are stationed the xedly attached lever 15a, the'fixedly attached paper-feeler 28, and the ixedly attached weight 66a.vThe platen isvsupplied with the `circuu'iferential slot or groove 4near the end, just beyond the i orking surface. u The paper sheetoverlaps this slot, and', upon the passing of the end thereof the.paper-feeler enters it, the function of the slot being exactly thatofthe sloty 4 in Fig. v1. And when the projection 14 clears thelever 15a,the parts automatically return into operative position, under theinfluence of the weight. A backing-up movementof the projection 14results in'an idle turning backward of thehub 21EL upon the axle 2Oa inthis arrangement, so that certain one-way flexion means shown in some ofmy other gures are not needed.

In Figs. 21 .and 22 the freely revoluble drum 6 bears the peripheralindices 6EL and.

the other signaling markings as before described; and it bears also theweight 25,'-

adapted to bring the indices into a suitable starting position when thedrum is released, from connection with the platen. vAt a momentdetermined by the paper-feeler 281 this drum is connected 'to rotatewith the platen. The paper-feeler here is provided'as before with aone-way flexion means', so that it will push idly backward before abacking-up bottom edge of the sheet through and out of the slot 4 inthepaper table 8,v without disyturbingthe position of the arm- 11.9bbearing 1t.` The structure is [as follows: 'Jourr naled in theframe-extension 124' upon the lever 118 and the arm 119D.

Vvsa

frame 12 is the axle 125, having fixedly attached thereto at one end thelever 126, and Xedly attached at the other the thumb- `The lever 126carries the pin 128', upon which is journaled the friction-roller 127adapted to make contact with the outerside ofdrum 6. The arm 11911vcarries the stop-pin 24", and the paper-feeler 28bwhich is hun on thepin 23b and the movements of whic 4are limited in one direction by thestop-pin. It also carries the pin 121, upon which is journaled theeccentrically balanced or weighted piece 122 having a segmentalperiphery 123 adapted to rest upon the surface of the'platen. When asheet is to be entered into the machine the operator presses downwardupon 'the lever- 118, thus raising the'paper-feeler 28" from its slotand raising also the. arm 126`bearing the friction-roller 127; Theresult is that the drum 6 is released from its frictional connectionwiththe platen. By this action the piece 122 is alsoV lifted clear andfalls into position as shown.' The operator can at once release thethumb-lever, for the.

piece 122 will now rest with its periphery upon the surface of theplaten and hold the paper-feeler sufficiently clear of the paper tabletopermit of the easy introduction of the sheet. The sheetis nowinserted, the platen turned forward, and, the end of the segment 123being reached, the paper-feeler will be lowered upon'the sheet, whichthereafter controls the position of the parts involved. lVhen the end ofthe sheet passes from under the paper-feeler the arm 119b is lowered,vvthereby pressing the friction-roller 127 againstthe drum 6 in such amanner as to force the," drum against the frictionwasher 11atv at theend of the platen, thus connecting the drum with the platen. From now onthe action of the indices 6a will be as has been described. In thisfigure I show indices intended to indicate the distance to the bottomline of a page that ends (say) five lines from the bottom edge of thesheet, instead of to thebottom edge itself.

Figs. 23 and 24 illustrate another arrangement of my sheet-controlledelements, the indices and their connection with the platen being thatshown in Fig. 1, but the paperfeeler28c being stationed to work fromunderneath the sheet upward, instead of from above the sheet downwardlThe structure is thisThe frame extension 136 bearsthe inwardlyprojecting axle 20C, and also the inwardly projecting plate 82, theplate lying above the paper table 8 at a distance convenient for theready-insertion. of the paper sheet between the two, and containing` theslotoropening 4. The axle 20c has journaled upon it the hub 21c-bearingfthe fixedly attached lever or arm "119, which is vstationed tolay` past the end of the paper table-8, and'in its normal .depressedposition meshes rests upon a fixed stop-pin 134. This arm in turn bearsthe inwardly projecting pin' 23C, upon which is mounted sleeve 21dcarrying the paper-feeler 28 and the weight 66g to restore thepaper-feeler to operativeposition, the two being attached the one to theother. To limit the movementof the paper-feeler inthe onedirection, thearm 119c bears the inwardly-projecting stop-pin 24C," againstl which theweight 66c engages, the purpose of the arrangementbeing as before tofurnish the paper-feeler with a one-way flexionmeans for use in abackingup movement of the sheet. As before, the lever` l5c is looselyjournaled upon the hub 21; and it isprovided with the lug 63c to engageagainst a second stop-pin 62C' on the arm 119C, the purpose whereof isto provide it with a one-way flexion means so that the projection 14 maybe backed up past it, the lever 15c lifting idly backward in such anaction. The hub 21c bearsalso the fixedly attached lever 7 4, and theframe 12 the inwardly-projecting pin 112C, between which the spring 111cexerts an adjustable pulling action, in order to counteract more or lesscompletely the weight of the lever 119, and its attached parts and inthis way to regulate the pressure of the paper-feeler Iupon the sheet.The paper table 8 contains the opening 133, through which thepaper-feeler 28c may play 4against the sheet, and when the sheet passeson, into the slot'4c in the plate 82, above the sheet.

In Fig. 25 my indices are carried upon a belt 6e running over t-hedriving pulleyr 112 attached to the platen, and a second pulley 153, thebelt having up'on it the project-ion 14e to coperate with the lever 15",and through it with the paper-feeler28e. The lever 15e is supplied withthe weight 146 to restore it into operative position, und with the pin63e to engage upon the arm 147 in a one-way ieXion means. The indices 6amay be duplicated upon the belt if desired, and the projection 14eduplicated, as shown, for use in printing small work. Thesheet-controlled elements are described thus: The frame extension 22ebears the axle 2()e fixedly attached to which are the crank-lever 150and the paper-feeler 28e. The rod 14S) furnishes a connecting means withthe lever 15" as shown, in consequence of being connected at its upperend to the arm v150 and at its lower end t-o pin 148 carried by arm 147.The action of the paper-feeler is substantially as before described,except that. instead of swinging lin a direction opposite to that of thepaper sheetas in Fig. 1 it swings in a direction following the sheet asin Fig. 19. It is to be noted that I omit the one-way flexion meansfor'the paper-fecler in this'arrangement, andv that the paperfeeler isretracted from the paper-path by the counter-balancing weight of the rodi t and the arms 147 and 150, instead of by the weight 66. It is to benoted also that in this arrangement the friction between the indices andthe platen is a belt friction, thatI is to say, a peripheral friction,`the pulley 112 and the belt 6e being the friction members, and what ismore, that it is an easable friction, since if the belt is slack thestop-l ping action of the lever 15e upon the pro` jection 14e will atthe same time tend to open the friction.

Figs. 2G, 27, 28 and 2 9 illustrate another modication in mysheet-controlled elements, the indices being carried and connected asshown in Fig. 1, upon .the 'friotionally-connected drum 6. In thismodification 'the paper-feeler 2Sf is shaped to lie flat upon the papertable under the paper sheet as a turned-in extension of the arm 119i,and the mask or plate 82 has a slot 4f shaped as shown in Fig. v2S toreceive it. Figs. 27 and 28 show these parts, and Fig. 29 isa view insection on the line D D showing them in the position they assume afterthe passage of the sheet and before their return into vfirst position.The secondary axis 23C, stop 24c and weight 66c of Figs. 23 and 24 areomitted, as is the opening 133 in the paper table. In other respects thestructure is essentially the same as that shown in Fig. 23, thepaper-feeler returning automatically by its own weight into firstposition when the projection 14 clears the lever or stop 15f, and thisfirst position being such as not to interfere with the entering sheet orlie in.

the way of the operator manipulating it.

Fig. is somewhat like Fig. 26 in structure, except that I add elementsadapted to raise and lower the plate Sg from and against the papertable, instead of allowing it to remain stationary. The structure isdescribed as follows: The frame extension 142 attached upon the carriageframe 12 bears the inwardly-projecting pin 144, upon which is journaledthe arm 119g, with its turned-in paper-feeler 28g. It also bears theinwardly-projecting pin 141, upon which is journaled the lever 139, thesaid lever being supplied with the `slot 140, the pin 20g, and the stop62g. Journaled upon this pin 20g is the piece 15g, bearing through thelug 63g upon *he said stop 62g so as to form in eifect an operativeextension of the lever 139 when its free end is acted upon downwardly,but when such end is acted upon upwardly lifting idly aside, the purposeof this structure being to provide for a backing-up movement. of theprojection 14, in whose path the piece 15g normally lies. The .lever119g bears the pin 143, upon .which is journaled the lever 137. Thislast-named lever carries the pin 138 working i-n the slot 140; and itbears the turned-in plate 8g, supplied with a feeler-receivino' slot oropening.` A spring 111g engaged.J by one, end

with 'the pin 112g pulls downwardly upon the lever 139 as shown, inorder to restore the working parts to their operative position. v Theaction of this mechanism is as follows: The sheet 45 is inserted uponthe `paper table 8, the paper-feeler 28g meanwhile lying flat upon thepaper table underneath it. VThe sheet is advanced, by rotating theplaten and eventually .the projection 14 presses against the piecelg.thereby lowering the plate 8g upon the sheet. Furthery pressure upon thepiece 15g tends to raise the paperfeeler 28g against the sheet. When thesheet passes on the paper-feeler passes into the slot in the plate 8g asbefore, these parts being shaped as shown in Figs. 27, 28 and 29,releasing the vlever 15g' from.A its stopping act-ion. The mechanismnow. enters upon its 'indicating action, substantially as described inconnect-ion with Fig. Il.

Fig. 31 is a modification showing how it is possible to omit all thesheet-controlled group of'elements except thc paper-feeler itself andthe cooperating slotted paper `table; and it also somewhatdiagrammatically illust-rates a modification in the form of easable vorreleasable frictional connection between the indices and the platen. Thedisk or pulley 56, attached to turn as a unit with the platen, hasextended around its periphery the friction-strap 57, attached ateither.. end to the pins 60 upon the lever 32. This lever is journaledupon the pin 53h on the drum G; and it is provided .with a tail 54h,against which presses the spring 5,5, also attached to the drum 6, thepressure of the spring tendingto tighten the strap upon the periphery ofthe part 5G. The lever 32bears upon its extremity theinwardly-projecting paper-feeler 28, in the path 101 of which lies theslot or opening 4h, in the paper table 8. The sheet` prevents theorbitallymoving paper-feeler from entering the, slot 4h, during itspresence over the slot, thus detaining the drum, but. in this casehaving fewer intermediate elements to work through. Its action is this:The lever 32, in effectpressed backwardly upon its axis 53h, loosens thefriction-strap 57, opening the frictional connection between the drumand the platen and permitting the drum to stop independently of theplaten; and at the same time the paper sheet acts, through thepaper-feeler, as a stopping agent, as it would do if the friction werenot supplied with an easing means. When the sheet passes on, the lever32 is released,the friction-strap 57 is tightened by the spring 55, andthe platen picks up ythe drum G with its indices as before. It is to benoted that in this arrangementI the paper-feeler. is ret-urned intooperative position automatically, and is removed out of the way of theentering sheet automatically. f

The

appear. The structure is as :tolloWsi The drinn G, reduced to a mereperipheral sheli having a light ti'iction-tiange, carries the indicesand signaling markings, and also the profection lak. On either side ofthe Flange l place the friction-dish; llaand l1", and against the-,disk11 the armed dish-'spring 7k, 'and against the spring the circular headpiece 1lb" having in the hub thereof the set-` screw 83.

The paper table8 is provided with the slot or opening d, through which the paper-teelermay pass.
